OUTBOARD-CONDENSER.

Specification of Letters Patent.

Patented June '7, 1921.,

Application filed May 21, 1919. Serial No. 298,701.

denser for ships and it has for an object to provide a simple and highly eflicient condenser of high capacity.

A. further object is to provide a condenser applied externally to the hull of the ship which will effect a rapid condensation of the steam and will not impede the passage of the ship.

For further comprehension of the inven-' tion, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings,

and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a plan view of a ship having my invention applied thereto.

Fig. 2 is a transverse section of the hull taken on the line 22 of Fig. 1.'

Fig. 3 is a fragmentary side elevation of a modified form of condenser.

Fig. 4 is an enlarged transverse section on the line 4-4 of Fig. 3. I Fig. 5 is a fragmental sectional view illus trating the application of my invention to the bottom of the hull of a vessel; and,

Fig. 6 is a fragmental elevational view of a corrugated outer plate. 7

My improved condenser may be applied to steamships to condense steam from the boilers of ships of any type to distil salt water. In the drawings the hull of a steamship is shown at 1, and in the plan view I have shown the funnels from the furnaces at 2.

In applying my improved condenser the usual plates of the hull 1 are preferably removed at points on opposite sides of the keel of the latter to receive the condensers as shown in Fig. 5, or the hull may be stepped inwardly at points on the sides thereof below the water line as indicated at 3 in Fig. 2.

The condensers comprise the narrow, elongated chambered members 5 which preferably extend, as shown, the major distance of the length of the ship.

The outer walls of these condenser members 5 are formed in longitudinally extendingcorrugations as shown at 6 which extend from end to end thereof. The outermost points of said corrugations are preferably substantially flush with the outer surface of the hull of the ship, while their innermost points extend in comparatively close proximity to the inner walls of the condenser members, this being shown clearly in the drawings.

Pipe 7 connects the forward end of the condenser chambers, this pipe being conf nected by the union indicated at 8, to the steam pipe 9. From the bottom of the opposite end of each condenser chamber pipes 9 connect to pumps 10 by which the condensed water is withdrawn from the condenser chambers and which may distribute it to any desired point. As shown in Fig. 6 the corrugations in the condensers may converge toward the rear, or outlet end, thereof.

In the modification shown in Figs. 3 and 4, the corrugations in the outer wall of the condenser chambers are arranged longitudinally in alternating sections 15, and 16, the convexities of one section being in alinement with the concavities of the adjacent section thus effecting a redistribution of the water several times as it passes longitudinally over the condenser.

As will be apparent I have produced a steam condenser for ships of exceedingly simple construction and of high capacity in which a maximum condensation will be effected with a minimum loss of power.

Having-thus described my invention and set forth the manner of its construction, what I claim as new, and desire to secure by Letters Patent is A steam condenser for ships comprising a chambered member'extending along the hull of the ship, the outer wall of said member being divided longitudinally into a series of longitudinally extending corrugated sections, the convexed elements of each section being in alinement with the concaved elements of the adjacent section.

In testimony whereof I have aflixed my
